While you might expect the toilet and the sink to have high levels of bacteria, researchers found more surprising items with high contamination levels, such as the remote and the switch on the bedside lamp — items you frequently touch first.

As for the germs in the rest of the room, researchers found that it’s the person assigned to cleaning your hotel room who may be spreading the bacteria.

Researcher Katie Kirsch found that the highest levels of contamination were found on the maid’s cleaning cart, specifically on the mop and sponge. That means that bacteria are being carried from room to room, she wrote.

While hotel rooms don’t have to be surgically sterile, researchers say there is certainly room for improvement: Bacteria levels in hotel rooms were between two to 10 times higher than the level accepted in hospitals, the study found.

The amount of bacteria on the remote may not mean that it’s “any dirtier than at home, but there’s a stranger factor” in a hotel room, study researcher Jack Neal, a microbiologist at the University of Houston, told MyHealthNewsDaily.com.

The lowest levels of bacteria were found on the headboard, curtain rods and bathroom door handle.

This doesn’t mean that the bacteria in your hotel room is going to make you sick, but it does raise the odds of it happening.

The one drawback is that this study was fairly small — only nine hotel rooms were tested in three states: Texas, Indiana and South Carolina.

The study was presented last week at the American Society for Microbiology conference in San Francisco.

Diabetes epidemic brings spike in related eye disease.USA Today reports that the nation’s rising level of diabetes is causing a significant jump in older adults with vision problems from a related condition called diabetic retinopathy. From 2000 to 2010, there was an 89 per cent increase in the number of people with diabetic retinopathy, which affects the tiny blood vessels of the retina and can impair vision. About 7.7 million people ages 40 and older have the disease, the new estimates say.
